Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ExlService Holdings, Inc. (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 29, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenues - Refer to Notes 2 and 4 to the financial statements

Critical Audit Matter Description

Revenue is recognized when services are provided to the Company’s customers, in an amount that reflects the consideration which the Company expects to be entitled to in exchange for the services provided. Revenue is measured based on consideration specified in a contract with a customer and excludes discounts and amounts collected on behalf of third parties. Revenues under time-and-material, transaction and outcome-based contracts are recognized as the services are performed.

At the inception of a new contract with a customer, the Company evaluates the revenue recognition principles, including judgments in identifying performance obligations in a contract and determining the timing of revenue recognition. The Company’s contracts may be modified to add, remove or change existing performance obligations, which require judgment to evaluate and determine whether they are to be accounted for on a prospective basis either as a separate contract, or as a termination of existing contract and creation of a new contract.

Auditing revenue recognition requires significant audit effort resulting from the number of customers and related contracts that require evaluation and auditor judgment as to whether revenue was recorded in accordance with the terms of the contracts and revenue recognition principles under Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”).

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to whether revenue was recorded in accordance with the terms of the contracts with the Company’s customers and met the criteria for revenue recognition in accordance with ASC Topic 606 included the following, among others:

•We tested the effectiveness of internal controls over revenue, specifically management’s controls over the identification of performance obligations within the customer contracts and determining timing of revenue recognition for new customer contracts and contracts with significant scope modifications.

•We selected a sample of recorded revenue transactions from new customer contracts and evaluated the appropriateness of the performance obligations identified within the customer contracts and assessed if the revenue recognition principles applied are in accordance with ASC Topic 606.

•We selected a sample of recorded revenue transactions related to the Company’s contracts that were modified to add, remove or change existing performance obligations and (1) assessed whether the services added to an existing contract are distinct and whether the pricing is at a standalone selling price; and (2) services added that are distinct and at standalone selling price are accounted for on a prospective basis either as a separate contract, or as a termination of existing contract and creation of a new contract.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
